Diamond burs are used for precise drilling and finishing and for grinding where material removal is not a concern. Diamond burs produce cleaner cuts and a higher polish than carbide burs. When choosing a diamond bur, consider its grit. The diamond bur's grit determines the speed and type of polish. Diamond burs with finer grits achieve a higher polish and finish while diamond burs with coarser grits are suited for heavy material removal. Diamond burs are either standard or disposable. Standard diamond burs are reusable and should be sharpened and sterilized before use in another procedure. Disposable diamond burs are designed for single use and should not be reused in another procedure.
